Manchester City's all-time top scorer Sergio Aguero could be out for the rest of the season after suffering a knee injury during Monday's 5-0 Premier League win over Burnley at The Etihad.

The striker will travel to Barcelona for further examination of the injury by a specialist with his club confirming: "The striker will now travel to Barcelona to see Dr Ramon Cugat for further examination. Everyone at City wishes Sergio the best with his recovery." 

Cugat, who has known Guardiola since the manager's days at Barcelona, has previously treated City players Kevin De Bruyne and Vincent Kompany among others, while Guardiola himself visited Cugat during his own playing days.

Aguero wrote on Twitter: "The scans I did this morning have confirmed that I have damaged my left knee.
"It's a pity but I'm in good spirits and so focused to come back as soon as possible. Thank you very much for all your messages!"

The game was overshadowed by a banner reading 'White lives matter Burnley' that was flown overhead but on the pitch City were dominant.

The outstanding Phil Foden opened the scoring with a superb low strike on 22 minutes and later completed the rout. Riyad Mahrez also struck twice, including a penalty, while David Silva netted the other.

The major downside for City was the loss of Aguero just before the interval.

"It doesn't look good. We are going to see tomorrow. He was struggling in the last month with a problem in the knee," said City manager Pep Guardiola.

"We will see what he has done but it doesn't look good for the season."

Aguero went down under a challenge from defender Ben Mee on the stroke of halftime with the Burnley captain ruled by VAR to have made contact with his foot.

The Argentine limped off to be replaced by Gabriel Jesus, the club's only other recognised central striker.

While second-placed City have next to no chance of catching leaders Liverpool, who have a 20-point lead with eight games remaining, the absence of Aguero will be a blow to Guardiola's Champions League hopes.

City lead 2-1 against Real Madrid from the away leg of their last 16 match and are hoping to reach August's 'Final Eight' of the competition in Lisbon.
